Description

Tyrhedyn is a house dated 1877, though it may be slightly older. It is constructed from brown rubble stone with blue slate banding and features a banded eastern end stack. The building has three storeys and a double front, characterized by paired bracket eaves and sash windows with marginal glazing bars. The small upper windows have painted brick cambered heads and painted slate sills, while the large first-floor windows are adorned with recessed painted stone voussoirs above their cambered heads and painted slate sills.

On the ground floor, there is a flat-topped canted bay to the left, which contains a similar sash window at the front and narrow sidelights. The central door features two arched panels and an overlight, set within a pilastered doorcase that has console brackets supporting a flat corniced hood. To the right, there is another sash window with recessed painted stone voussoirs. The house has a painted slate plinth, and the eastern end attic wall displays a plaque indicating that the pine end belongs to Stephen Evans, dated 5 October 1877.

The front area of the property is enclosed by spearhead iron railings atop a dwarf slate-coped wall.
